本文介绍了如何使用karma / jasmine测试browserify项目的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我对测试的概念完全陌生,我需要一个关于如何在我的项目中做到这一点的实例:



我有一个gulp文件去像这样(不是全部,只是重要的部分)

  gulp.task('bundle',function(){
gulp.src('public / angular-app / main.js')
.pipe(browserify({
debug:true
}))
.pipe( gulp.dest('public / min-js'));
});

这是我的main.js的一小部分:

 'use strict'; 

angular.module('myApp',[
'ui.router',
'ui.bootstrap',
'ngSanitize',
' ngFx',
...
],['$ interpolateProvider',
函数($ interpolateProvider){
$ interpolateProvider.startSymbol('{{');
$ interpolateProvider.endSymbol('}}');
}
])

.config(require('./ config / routes'))

.config(require('。/ config / authInterceptor'))
.run(require('./ config / runPhase'))
.run(require('./ config / xeditable) '))



.controller('homeController',require('./ controllers / homeController'))
.controller('modalInstanceCtrl',require( './controllers/modalInstanceCtrl'))
.controller('modalparticipantCtrl',require('./ controllers / modalParticipantCtrl'))
.controller('generatorControlle r',require('./ controllers / generatorController'))
.controller('navController',require('./ controllers / navController'))
.controller('signInController',require(' ./controllers/signInController'))
.controller('pricingController',require('./ controllers / pricingController'))
.controller('howItWorksController',require('./ controllers / howItWorks' ))
...

现在这是我的karma配置文件:

  module.exports = function(config){
config.set({

// base将用于解决所有模式的路径(例如文件,排除)
basePath:'',


//框架使用
//可用框架:https://npmjs.org/browse/keyword / karma-adapter
frameworks:['jasmine'],


//在浏览器中加载的文件/模式列表
文件:[
'public / vendor / jquery / dist / jquery.js',
'public / vendor / angular / angular.js',
'public / vendor / angular-mocks / angular-mocks.js' ,
'public / angular-app / ** / * .js',
'test / ** / * Spec.js'
],


//要排除的文件列表
排除:[
],

当我用业力开始运行业力时,这就是我得到的:



未被捕获的参考错误:未定义在root / public / angular-app中的
/main.js



所以我的问题很简单,我怎样才能进行测试,例如,在我的homeController上...



//更新



所以我更新了我的测试文件对此:

  describe(一个Angularjs测试套件,function(){
var target,rootScope;
beforeEach(inject(function($ rootScope){
rootScope = $ rootScope;

//在这里模拟所有内容
spyOn(rootScope,$ on)
}));

beforeEach(inject(function(homeController){
target = homeController;
}));

it('应该调用rootScope。$ on',function(){
expect(rootScope。$ on).toHaveBeenCalled();
});

});

和我的配置文件:

  //要在浏览器中加载的文件/模式列表
文件:[
'public / vendor / jquery / dist / jquery.js',
'public / vendor / angular / angular.js',
'public / vendor / angular-mocks / angular-mocks.js',
'public / min-js / main.js',
'test / ** / * Spec.js'
],


//要排除的文件列表
不包括:[
],


browserify:{
watch:true,
debug:true
},

预处理器:{
'test / *':['browserify']
},

仍然没有任何作用,首先他说'未知提供者homeControllerProvider',
现在,如果我删除它们行:

  beforeEach(注入(function(homeController){
target = homeController;
}));

它仍然给我错误,预期间谍$ on会被调用,我如何解决这个问题? / p>

解决方案

在运行测试之前,您需要通知Karma运行Browserify。



您可以在您的Karma配置中添加:

  {
browserify:{
watch:true,
debug:true
},
预处理器:{
'test / *':['browserify']
}
}

Karma配置文件参考: http://karma-runner.github.io/0.12/config/configuration-file.html



<或者看看我使用Karma进行测试的项目之一: smild


I'm totally new to the concept of testing, and i need one solid example on how to do it in my project:

I have a gulp file goes like this (Not all of it, just the important portions)

gulp.task('bundle', function() {
    gulp.src('public/angular-app/main.js')
        .pipe(browserify({
            debug: true
        }))
        .pipe(gulp.dest('public/min-js'));           
});

This is a slight portion of my main.js:

'use strict';

    angular.module('myApp', [
        'ui.router',
        'ui.bootstrap',
        'ngSanitize',
        'ngFx',
        ...
    ], ['$interpolateProvider',
        function($interpolateProvider) {
            $interpolateProvider.startSymbol('{{');
            $interpolateProvider.endSymbol('}}');
        }
    ])

    .config(require('./config/routes'))

        .config(require('./config/authInterceptor'))
        .run(require('./config/runPhase'))
        .run(require('./config/xeditable'))



        .controller('homeController', require('./controllers/homeController'))
        .controller('modalInstanceCtrl', require('./controllers/modalInstanceCtrl'))
        .controller('modalparticipantCtrl',require('./controllers/modalParticipantCtrl'))
        .controller('generatorController',require('./controllers/generatorController'))
        .controller('navController', require('./controllers/navController'))
        .controller('signInController', require('./controllers/signInController'))
        .controller('pricingController', require('./controllers/pricingController'))
        .controller('howItWorksController',require('./controllers/howItWorks'))
        ...

Now this is my config file for karma:

module.exports = function(config) {
  config.set({

    // base path that will be used to resolve all patterns (eg. files, exclude)
    basePath: '',


    // frameworks to use
    // available frameworks: https://npmjs.org/browse/keyword/karma-adapter
    frameworks: ['jasmine'],


    // list of files / patterns to load in the browser
    files: [
      'public/vendor/jquery/dist/jquery.js',
      'public/vendor/angular/angular.js',
      'public/vendor/angular-mocks/angular-mocks.js',
      'public/angular-app/**/*.js',
      'test/**/*Spec.js'
    ],


    // list of files to exclude
    exclude: [
    ],

When i run karma with karma start this is what i get:

Uncaught reference error:require is not defined at root/public/angular-app/main.js

So my question is simple, how can i do tests, for example, on my homeController...

//update

So I updated my test file to this:

describe("An Angularjs test suite",function(){
    var target, rootScope;
    beforeEach(inject(function($rootScope) {
      rootScope = $rootScope;

      // Mock everything here
      spyOn(rootScope, "$on")
    }));

    beforeEach(inject(function(homeController) {
      target = homeController;
    }));

    it('should have called rootScope.$on', function(){
      expect(rootScope.$on).toHaveBeenCalled();
    });

});

and my config file to this:

// list of files / patterns to load in the browser
files: [
  'public/vendor/jquery/dist/jquery.js',
  'public/vendor/angular/angular.js',
  'public/vendor/angular-mocks/angular-mocks.js',
  'public/min-js/main.js',
  'test/**/*Spec.js'
],


// list of files to exclude
exclude: [
],


browserify: {
        watch: true,
        debug: true
},

preprocessors: {
    'test/*': ['browserify']
},

Still nothing works, first he says 'unknown provider homeControllerProvider', Now if i delete them lines:

beforeEach(inject(function(homeController) {
          target = homeController;
        }));

it still gives me error, expected spy $on to be called, How do i fix this?

解决方案

You need to inform Karma to run Browserify before running tests.

You can add this in your Karma config:

    {
        browserify: {
            watch: true,
            debug: true
        },
        preprocessors: {
            'test/*': ['browserify']
        }
    }

Karma config file reference: http://karma-runner.github.io/0.12/config/configuration-file.html
